Problems solved by technology

In practical applications, these two methods require constant-speed sampling, heavy instruments, poor operability, heavy workload, and are easily limited by site conditions. Moreover, the condensation method is subject to the mixing of evaporated water and flue gas water, and the dehydration method is limited. The influence of the dehydration efficiency of the dehydrator, so the measurement error is relatively large. In addition, these two methods are difficult to meet the requirements of real-time display

Embodiment Construction

[0034] The invention starts from the principle of material balance and heat balance, and establishes a mathematical model of the amount of water carried in the flue gas. As long as the relevant parameters are measured according to the actual situation and brought into the formula calculation, the amount of water carried in the flue gas under the actual working condition can be obtained. see figure 1 , the mass balance and heat balance under the working conditions of wet dust collector or wet desulfurization device are shown in the figure, and the following mass balance exists in this system:

[0035] Q 1 +ΔQ=Q 2 (1)

[0036] G 1 +G 2 =ΔG 1 +ΔG 2 +G 3 (2)

[0037] where Q 1 ——Inlet flue gas volume, Nm 3 / h;

[0038] Q 2 ——Outlet flue gas volume, Nm 3 / h;

[0039] ΔQ——air leakage volume, Nm 3 / h;

[0040] G 1 ——water consumption for cooling at import, kg / h;

[0041] G 2 ——Water consumption of cylinder, ...

Abstract

The present invention relates to a method for measuring water content carried by the smoke in wet desulfurating or dust-removing equipment, belonging to the field of measurement technology, Said invention provides a computing formula for measuring water content delta G carried by unit smoke. Only according to said formula requirements the correspondent parameters are measured, the water content carried by unit smoke can be conveniently and easily obtained.

Description

technical field [0001] The invention relates to a method for measuring water in flue gas of a wet desulfurization or dust collector device, and belongs to the field of measurement technology. Background technique [0002] Wet desulfurization devices or wet dust collectors are commonly used desulfurization and dust removal devices. These devices have water in the flue gas to varying degrees during operation, which seriously affects the safe operation, service life and environmental protection of the equipment. The hazards are: the accumulation of wet ash in the outlet flue and the intake smoke box of the suction fan, causing a sharp increase in the resistance of the flue, and even limiting the output of the boiler; or the dust sticking to the blades of the suction fan, causing the fan to vibrate, corrode, or even "speeding"; It will also affect the diffusion of smoke exhaust, causing serious phenomenon of gray water clusters falling around the factory area and polluting the e...
